Material examined

Holotype female, CHINA: Guanshan, 430 m, Yifeng County, Jiangxi Province, 20 April 2009, leg. Ling-Li Yi and Yi Li (GSFPM).

Description

Habitus: Fig. 4. Female. Body length 10.5 mm. Fore wing length 7.6 mm. Ovipositor length about 1.5 mm.

Head

Face approximately flat, 1.4 × as wide as long, with even punctures, distance between punctures 0.2 to 1.0 × diameter of puncture, lateral sides (inner orbit) impunctate and with fine granular texture. Clypeus nearly flat, about 2.2 × as wide as long, with fine, sparse punctures, distance between punctures 2 to 4 × diameter of puncture, apical portion smooth, impunctate. Labrum crescentic, about 0.33 × as long as wide. Malar space with fine leathery texture, without subocular sulcus, approximately 0.4 × as long as basal width of mandible. Gena glossy, with distinct fine punctures, in lateral view approximately 0.66 × as long as width of eye, evenly convergent backward. Posterior portion of vertex with fine punctures, portion between lateral ocellus and eye with fine leathery texture. Interocellar area slightly convex, with fine longitudinal wrinkles. Postero-ocellar line approximately as long as ocular-ocellar line. Dorsolateral part of frons with fine punctures, distance between punctures about as long as diameter of puncture; median portion narrowly smooth longitudinally; ventral portion with weak median longitudinal carina reaching to median protuberance of face. Antenna 5 mm, with 20 flagellomeres, ratio of length of flagellomere 1:2:3:4:5 is 5.5:4.0:3.8:3.7:3.4; last flagellomere 3 × as long as wide, approximately as long as fourth flagellomere. Distance from hypostomal carina to mandible about as long as basal width of mandible.

Mesosoma

Anterior portion of pronotum with fine longitudinal wrinkles; dorsal portion slightly scabrous; near dorsomedian portion with transverse wrinkles, posterior sections of the wrinkles parallel dorsal margin of pronotum; ventral portion with dense transverse wrinkles. Epomia indistinctly differentiated from strong oblique wrinkles. Mesoscutum with fine punctures; punctures on middle lobe denser than on lateral lobe, distance between punctures 0.2 to 2.5 × diameter of puncture; distance between punctures on lateral lobe 0.5 to 3.5 × diameter of puncture; posterior median portion with longitudinal concave and transverse wrinkles. Scutellum with dense punctures, distance between punctures 0.2 to 0.5 × diameter of puncture. Postscutellum with relatively large, elongate punctures. Lower portion of mesopleuron slightly scabrous, with dense punctures; dorsoanterior portion, in front of subalar prominence, with short longitudinal wrinkles; median portion (anterior to speculum) and ventroposterior portion with short transverse wrinkles. Speculum relatively large. Mesosternum densely punctate. Median longitudinal suture of mesosternum distinct, slightly widening posteriorly. Metapleuron scabrous, with irregular, elongate punctures. Metasternum elongate, approximately 0.6 × as long as mesosternum, with distinct median longitudinal carina and irregular transverse wrinkles. Wing hyaline with slight grey tinge. 2rs-m basad 2m-cu by 0.66 × length of 2rs-m. Vein 2-Cu as long as 2cu-a. Hind coxa with distinct punctures. Ratio of length of hind tarsomeres 1:2:3:4:5 is 10.0:4.2:2.9:2.0:4.2. Propodeum between carinae with distinct transverse wrinkles. Propodeal spiracle 1.4 × as long as maximum width, distance to pleural carina approximately 2.6 × as long as distance to lateral longitudinal carina.

Metasoma

First tergum approximately 5 × as long as apical width, with longitudinal wrinkles, between wrinkles with punctures; without longitudinal carina; spiracle convex, located at basal 0.42. Second tergum about 2.0 × as long as apical width, slightly widened posteriorly, with sparse, indistinct punctures. Third tergum with even, fine hairs, gradually weaker and indistinct posteriorly. Ovipositor sheath about 0.27 × as long as hind tibia. Ovipositor very slightly compressed.

Colour

Black. Ventral, inner orbits, clypeus, stripe passing through anterior tentorial pits, mandible except teeth, yellow; ventral profile of antenna brown to yellowish brown. Labial and maxillary palpi, fore and mid legs, trochantellus of hind leg, hind tarsomeres buff. Apex of hind coxa, ventral profile of trochanter of hind leg, basal and apical portion of hind femur brown. Basal 0.65 of hind tibia dull yellow, fading to dark brown apical 0.35. Tegula dark brown. Hind margins of terga 3 to 6 narrowly yellow. Wing venation, including pterostigma dark brown.

Etymology

Named after the country, China, where the unique specimen was collected.

Diagnosis

A distinctive species with the short, featureless ovipositor, rather massive hind leg, lobate fore and mid claws, short antennae and well-marked facial pattern.
